Interest in DIY CDI

[_Adrian_]

Hey guys and gals...
Been on a break for a good while now and was looking to give back to the community a bit

I been slowly wrenching on project and was thinking why not add in a CDI, as the hotter the spark the cleaner the burn specially on richer mixtures would help quite a bit.

Anyone ??

SO!

The simple part would be the power supply...
- Feasible, that's capable of boosting 12V to somewhere in the neighborhood of 250 to 300V while keeping it fairly simple.
- High Current, capable of at least 1 - 2.5A of current. This would be more than enough to satisfy most "enthusiasts" out there specially when having a good "reserve" ( low ESR, high value caps for energy storage ).
- SAFE...the high voltage part would have to be fully potted and only items would be exposed would be the connectors ( Power, HVOut ). Bleed resistors are a must to drain the high capacitance storage bank for when the unit is not in use or being serviced ( in event of a failure )!!
The supply itself would most likely going to be a regulated DC/DC Inverter. I do have a few older schematics I could use, but the point of this exercise is to develop a newer more efficient system capable of maintaining low noise / low ripple and high efficiency.

Plenty of tools out there to help with this endeavor...

Now for the harder part...
This is where the "FUN" begins!

Multi Channel Unit 2/4/6/8 Channel CDI that's capable of dropping a shower of spark for each and every ignition event ( up to 12 sparks at lower RPM's and 2-4 sparks at 7000RPM ) would ALMOST require a processor... or does it ???

This can be built very simply or immensely complex!
The Simple path would be to create one circuit and clone it the number of times needed to achieve your desired number of outputs, meanwhile the other route would be a more complex microprocessor / microcontroller unit which would be more efficent and more flexible where as it would be less DIY friendly.

Now lets hear your constructive criticism
